Our drying drum is fitted with a high performance reducing motor which is connected to a supporting wheel (made of heat-resistant nylon) through universal joints. Friction makes drying drum run. The drying drum is also equipped with an elastic inflation gasket. This reduces the noise and prolongs the service life.

(2) Imported oil burner

The oil burner used is of an internationally renowned brand. The newest international flame control licensed technology is used for its construction. The oil burner is a fully automatic numerically controlled burner that uses any kind of heavy oil and residual oil produced by any refinery in China.
The advanced oil supplying system enables the heavy oil and residual oil to be atomized and burned. It can save 7-15% of oil, and the flame regulating ratio can reach 10:1.

Through the liquid crystal display screen, you can monitor and modify system parameters and see disturbance messages. All the component elements are controlled and performed by PLC, making the operation easy and convenient.
Compared to other burners, our burner has many advantages:
It adopts advanced technology and is intellectualized.
It has appropriate structure, high safety and high cost performance.
It has various features such as low consumption, low wearing, low noise and low levels of pollution.

3. Hot aggregate elevating, screening, storing and weighing system

(1) Hot aggregate elevator

Hot aggregate elevator is a chain type efficiency elevator. Matched sleeve roller chain is made of alloy steel. Among its features include steady running, friction resistance, low noise, low malfunction and long using life, etc. Meanwhile, the chain is equipped with an automatic tension device and anti-reversing electromagnetism reducing motor. All these enables hot aggregate elevator to work safely, reliably and efficiently.

(2) Vibrating screen

Our asphalt mixing plant is designed with a vibrating screen. The screen is fixed by a quick draw hook device which makes the replacement of screen more convenient.
The whole screen is connected by durable bolts and is enclosed in a dust proof cover. The dust proof cover is environmental-friendly and has a charging port and dust collecting port.
The vibrating sieve is equipped with a motor anti-phase device which prevents jumping and abnormal movement when the vibrating screen is stopping.

(3) Storage

Hot aggregate bin and continuous type charge level indicator Our asphalt mixing plant is furnished with a high-capacity hot aggregate bin which ensures the continuous discharge of finished products. The exterior of bin is covered by a heat preserving layer, which reduces heat loss, lowers fuel consumption and reduces costs.
Each hot aggregate bin is equipped with a continuous type charge level indicator which continuously displays the variation of charge levels. A thermal resistance thermo detector is installed on sandstone scraps bin to test the temperature of the sandstone. A hopper gate is specially designed to avoid blockage. The collecting bin at the end of the overflowing pipe and waste pipe provides convenient collection and transportation of the overflow and waste material.

(4)Weighing system

The equipment has three weighing hoppers:
Sandstone measuring hopper
It is a specially designed eccentric hopper which makes it convenient to open the hopper. The pressure relief pipeline helps remove what is unwanted.

4.Mixing system

The mixer has a square frame design and works in a stable and safe way.
Both the scale board and blade are made of white high chrome wear-resistant cast iron to give a long operating life.
The mixer has an overturning type charging gate, which is controlled by double cylinders, to shorten the charging time and achieve good sealing effectiveness.
The filling rate is no more than 60% to ensure that the stones and asphalt are completely mixed within a short time.
Reliable lubricating system
With an automatic lubricating system, a 380V mightiness motor is used to pump the lubricating oil to the point of lubrication. Manual lubricating can also be carried out.

5. Hot-conducting oil heating and asphalt supplying system

This device adopts a fully automatic horizontal heat conducting oil heating system (modularize transportation and installation). The imported burner has the functions of automatic ignition and monitoring. The fire of the burner can be adjusted according to thetemperature of heat conducting oil.

6.Dust removal system
